So easy Webservice 7.CXF 发布WebService

（一）使用ServerFactoryBean 方式实现发布WS服务

1.新建项目，添加cxf jar包到项目中

2.编写服务实现类

/**
 * CXF WebService
 * 不用注解
 * @author mlxs
 *
 */
public class CXFWebService {

    public String sayHello(String name){
        return "hello," + name;
    }

}

3.编写服务发布类

/**
 * CXF 使用ServerFactoryBean发布WS服务，采用编码方式
 * 这种方式不好：不支持注解，不能修改WSDL文件
 *         如设置服务名称无效：
 *         @WebService(
 *            serviceName="cxfHelloService"
 *        )
 * @author mlxs
 *
 */
public class CXFPublishWS {

    public static void main(String[] args) {
        String address = "http://127.0.0.1:2345/cxfHello";
        ServerFactoryBean factoryBean = new ServerFactoryBean();
        //设置服务地址
        factoryBean.setAddress(address);
        //设置服务实现类
        factoryBean.setServiceBean(new CXFWebService());
        //发布WS
        factoryBean.create();
        
        System.out.println(address + "?WSDL");
    }
}

4.访问WSDL地址：http://127.0.0.1:2345/cxfHello?WSDL

5.总结：

这种方式不好：不支持注解，不能修改WSDL文件
* 如设置服务名称无效：
* @WebService(
* serviceName="cxfHelloService"
* )

（二）下面使用支持注解，支持日志的发布方式：

1.创建CXF WS实现类 可以支持注解：自定义服务名

/**
 * CXF WebService
 * @author mlxs
 *
 */
@WebService(
        serviceName="CXFWs1"
)
public class CXFWebService {

    public String sayHello(String name){
        return "hello," + name;
    }
}

2.创建发布类

/**
 * CXF 使用JaxWsServerFactoryBean发布WS服务，采用编码方式
 * 这种方式：
 * 1.支持注解
 * 2.可以打印日志
 * @author mlxs
 *
 */
public class CXFPublishWS {

    public static void main(String[] args) {
        String address = "http://127.0.0.1:2345/cxfJaxWsHello";
        JaxWsServerFactoryBean factoryBean = new JaxWsServerFactoryBean();
        //设置服务地址
        factoryBean.setAddress(address);
        //设置服务实现类
        factoryBean.setServiceBean(new CXFWebService());
        //支持日志：在有请求进来、和返回给客户端的时候打印日志
        factoryBean.getInInterceptors().add(new LoggingInInterceptor());
        factoryBean.getInInterceptors().add(new LoggingOutInterceptor());
        //发布WS
        factoryBean.create();
        
        System.out.println(address + "?WSDL");
    }

}

运行后：

2016-1-27 23:13:37 org.apache.cxf.service.factory.ReflectionServiceFactoryBean buildServiceFromClass
信息: Creating Service {http://jaxws.cxfws.ws.mlxs.com/}CXFWs1 from class com.mlxs.ws.cxfws.jaxws.CXFWebService

http://127.0.0.1:2345/cxfJaxWsHello?WSDL

3.访问WSDL地址（Get请求）：

控制台日志：

2016-1-27 23:16:30 org.apache.cxf.interceptor.AbstractLoggingInterceptor log
信息: Inbound Message
----------------------------
ID: 1
Address: http://127.0.0.1:2345/cxfJaxWsHello?WSDL
Http-Method: GET
Content-Type: 
Headers: {Accept=[text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8], accept-encoding=[gzip, deflate, sdch], Accept-Language=[zh-CN,zh;q=0.8], Cache-Control=[max-age=0], connection=[keep-alive], Content-Type=[null], Host=[127.0.0.1:2345], Upgrade-Insecure-Requests=[1], User-Agent=[Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.101 Safari/537.36]}
--------------------------------------

4.使用wsimport下载源码，放到client工程中，执行访问WS接口：

public static void main(String[] args) {
        CXFWs1 ws = new CXFWs1();
        CXFWebService port = ws.getCXFWebServicePort();
        
        System.out.println(port.sayHello("administrator"));
    }

客户端输出：
hello,administrator

服务端日志：
2016-1-27 23:21:41 org.apache.cxf.interceptor.AbstractLoggingInterceptor log
信息: Inbound Message
----------------------------
ID: 4
Address: http://127.0.0.1:2345/cxfJaxWsHello

Payload: <?xml version="1.0" ?><S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/"><S:Body><ns2:sayHello xmlns:ns2="http://jaxws.cxfws.ws.mlxs.com/"><arg0>administrator</arg0></ns2:sayHello></S:Body></S:Envelope>
--------------------------------------

（三）WebService总结

1.ws访问流程： 在调用方法的时候先发送一条get请求去访问远程的wsdl文件(此文件中有相应的公共接口和可以调用的方法),此流程称为"握手"
2.然后在客户端发送 post请求传输 soap数据交给服务器,最后服务器返回soap格式给客户端
3.前面所讲的ws服务都是硬编码的服务, Service应该是单例模式, 如果有Spring，CXF应该需要交给Spring管理
